DELL PowerEdge R640 4LFF 1x Xeon Gold 6140 128GB rack server

Dell PowerEdge R640 4LFF for scale-out compute

The Dell PowerEdge R640 4LFF is a 1U rack server fitted with one Intel Xeon Gold 6140 processor running at 2.3GHz and 128GB of DDR4 ECC registered memory. It targets buyers who need dense, two-socket capacity in a compact chassis for virtualisation or database workloads. The PERC H740P RAID controller manages up to four 3.5-inch SATA drive bays. A 10GbE 562T dual-port adapter handles network connectivity.

Installation notes for the R640 chassis

The server ships with BIOS and firmware updated to the latest stable version and passes full burn-in diagnostics before dispatch. Rail kits are available on request and are not included by default. The 4LFF chassis accepts only 3.5-inch drives; 2.5-inch devices cannot be mounted without a separate adapter. Buyers who need more than four drive bays or a different backplane layout should choose another platform.

Sustained load behaviour with dual 750W supplies

Two 750W power supplies provide redundancy for continuous operation in a rack environment. The Xeon Gold 6140 delivers 18 cores with 24.75MB cache for steady multi-threaded throughput. iDRAC9 Enterprise remote management allows monitoring of thermals and power draw without host OS involvement. Memory scales to 7.68TB when a second processor is added for workloads that outgrow the single-socket configuration.
